Our meta-analysis of available randomized controlled trials demonstrated that ECTR and OCTR were similar in relief of symptoms, but ECTR resulted in better recovery of function and earlier return to work and was safer than OCTR.
Background. The purpose of this meta-analysis was to find out whether the proximal femoral nail was better than the dynamic hip screw in the treatment of trochanteric fractures with respect to operation time, blood transfusion, hospital stay, wound complications, number of reoperation, and mortality rate. Methods. All randomized controlled trials comparing proximal femoral nail and dynamic hip screw in the treatment of trochanteric fractures were included. Articles and conference data were extracted by two authors independently. Data was analyzed using RevMan 5.1 version. Eight trials involving 1348 fractures were retrieved. Results. Compared with DHS fixation, PFN fixation had similar operation time (95% CI: −15.28–2.40, P = 0.15). Blood loss and transfusion during perioperative time were also comparable between the two fixations (95% CI: −301.39–28.11, P = 0.10; 95% CI: −356.02–107.20, P = 0.29, resp.). Outcomes of hospital stay (95% CI: −0.62–1.01, P = 0.64), wound complication (95% CI: 0.66–1.67, P = 0.82), mortality (95% CI: 0.83–1.30, P = 0.72), and reoperation (95% CI: 0.61–1.54, P = 0.90) were all similar between the two groups. Conclusion. PFN fixation shows the same effectiveness as DHS fixation in the parameters measured.
BACKGROUND: Chemotherapy, target therapy, and immunotherapy are increasingly being used in the systematic treatment of nasopharyngeal carcinoma (NPC), during which the occurrence of hepatitis B virus (HBV) reactivation might increase. However, data regarding HBV screening and reactivation and the clinical management of NPC patients with HBV infections are lacking. This study was aimed at clarifying the risk of reactivation for NPC patients on different regimens while providing evidence concerning HBV screening and management in an endemic area. METHODS: With the NPC database from an established big-data intelligence platform at Sun Yat-Sen University Cancer Center in China, NPC patients who were diagnosed between 2008 and 2016 and underwent HBV screening and regular monitoring of liver enzymes and HBV deoxyribonucleic acid (DNA) were analyzed. RESULTS: Among the 46,919 patients identified, the HBV screening rate was 24.8% (11,616 of 46,919). Among the screened patients with an HBV infection, regular monitoring of liver enzymes and HBV DNA occurred for 563 patients. The incidence of HBV reactivation and HBV-related hepatitis was 9.1% (51 of 563) and 2.5% (14 of 563), respectively. The reactivation risk varied for different treatments and regimens and ranged from 0.0% to 21.4%. Detectable baseline HBV DNA (odds ratio [OR], 2.93; P < .01), the presence of liver metastasis at diagnosis (OR, 7.19; P < .01), and antiviral prophylaxis (OR, 0.29; P < .01) were significantly associated with reactivation. CONCLUSIONS: In NPC patients with chronic HBV infections on high-risk regimens, the reactivation risk is similar to or exceeds the risk associated with other immunosuppressive therapies for which screening and prophylaxis are recommended. Our findings, therefore, support HBV screening and prophylaxis for these patients, whereas regular monitoring might be appropriate for patients with resolved HBV infections or those receiving low-risk regimens.

In relieving pain and improving self-report function, PRP showed no superiority over hyaluronic acid in well-designed double-blind trials, and beneficial effects of PRP in most trials probably resulted from insufficient blinding methods. However, PRP is still considered more effective than placebo on the basis of present evidence.
PurposeConditional survival (CS) provides important information on survival for a period of time after diagnosis. Currently, information on CS patterns of patients with nasopharyngeal carcinoma (NPC) is lacking. We aimed to analyze survival rate over time and estimate CS for NPC patients using a national population-based registry.Materials and MethodsPatients diagnosed with NPC between 1973 and 2007 with at least 5-year follow-up were identified from the Surveillance Epidemiology End Results registry. Traditional survival rates and crude CS estimateswere calculated using Kaplan-Meier analysis. Risk-adjusted survival curves were plotted from the proportional hazards model using the correct group prognosis method.Results registry. Traditional survival rates and crude CS estimateswere calculated using Kaplan-Meier analysis. Risk-adjusted survival curves were plotted from the proportional hazards model using the correct group prognosis method.ResultsFor 7,713 patients analyzed, adjusted baseline 5-year overall survival improved significantly from 36.0% in patients diagnosed in 1973-1979, 41.7% in 1980-1989, 46.6% in 1990-1999, to 54.7% in 2000-2007 (p < 0.01). CS analysis demonstrated that for every additional year survived, adjusted probability of surviving the next 5 years increased from 66.7% (localized), 54.0% (regional), and 35.3% (distant) at the time of diagnosis, to 83.7% (localized), 75.0% (regional), and 62.2% (distant) for patients who had survived 5 years. Adjusted 5-year CS differed among age, sex, tumor histology, ethnicity, and stage subgroups initially, but converged with time.ConclusionTreatment outcomes of NPC patients have greatly improved over the decades. Increases in CS become more prominent in patients with distant disease than in those with localized or regional disease as patients survive longer. CS provides more dynamic prognostic information for patients who have survived a period of time after diagnosis.
In an era of unprecedented urbanization, population and industrial growth pressure is serious threat for the water management in Pakistan in present days. Water pollution from raw sewage, industrial wastes, and agricultural runoff limited natural fresh water resources in the country. Human health is facing serious problems due to deteriorating drinking water quality. Current review paper provides an insight to the water quality problems in Pakistan with an attempt to emphasize the challenges of water laws enforcement. Although Pakistan has developed many water laws the state of implementation is dominant, intermediate pollution crises are still remaining. We could come to the conclusion that strictly enforcement is compulsory for water environment regulations in Pakistan. Moreover, it is necessary to establish a reliable risk assessment system for water quality, human health and ecological safety.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
